Differential diagnosis

Synagelides longus resembles S. palpalis Żabka, 1985 (Żabka 1985: figs 573–580; Fig. 17D) in the general shape of the copulatory organs and habitus, but differs in: 1) retrolateral tibial apophysis is shorter than half the cymbial length, slightly broadened medially and curved apically in retrolateral view

in S. longus (Fig. 9B), whereas longer than half the cymbial length, tapered and straight in S. palpalis (Fig. 17D); 2) epigynal hood is about two times wider than long in S. longus (Fig. 10A), whereas about two times longer than wide in S. palpalis (Żabka 1985: fig. 577).
